S.J. Koch Duffy's electric boats are eco-conscious, as they don't burn any fuel. Emitting zero emissions, the 22- and 18-foot rental boats provide breathtaking views upon departure from any of the company's two regional watery locales. Based on the harbor of choice, renters can take the canopied vessels floating by Annapolis's US Naval Academy, along the waterfront restaurants of Baltimore's Inner Harbor. On board, a built-in stereo system emits an energetic score to each renter's adventure. Duffy's website claims the boats are as easy to drive as a golf cart, but also offers training for new drivers. Self-propelled adventures are also popular, as the company also rents paddleboats and kayaks.
